Aluminum Roller Rockers Arms 1.6 Ratio 3/8" Stud for Chevy Small Block 350 400

Aluminum Roller Rockers Arms 1.6 Ratio for Chevy Small Block 350 400

These aluminum roller rocker arms use a 1.6 ratio and 3/8 inch stud mount to transfer camshaft lift to the valves on Chevy small block 350 and 400 engines.

Overview

These aluminum roller rocker arms are a valvetrain component that pivots on a trunnion and rolls over the valve tip to reduce friction and side loading. The 1.6 ratio multiplies cam lift for stronger valve action. A practical choice for Chevy small block 350 and 400 builds that need durable, consistent valvetrain geometry.
